Changing Print Drum Sizes - Universal MS-120NI Owner's Manual

MOUNTING CONFIGURATION CONVERSION

The Universal Midsize Coders have been designed to accommodate three different print drum diameters. Mod-

els MS-120/MS-220 have a 12" circumference print drum, models MS-150/MS-250 have a 15" circumference

print drum and models MS-180/MS-280 have a 18" circumference print drum. The Field converting from one

model to the other is very quick and easy (See Figure 47).

NOTE: Models prior to January 1, 2011, cannot convert to the MS-180 or the MS-280, 18" print drum

because the baseplates don't have slot #3.

1-Remove the two mounting screws and delrin washers from the inking system baseplate. These items

are located on either side of the bottom of the coder.

2-Lift the inking system assembly away from the coder baseplate and reposition the eccentric pin in the

appropriate slot. 12" circumference print drums are positioned in slot # 1, 15" circumference print

drums are positioned in slot # 2 and the 18" circumference print drums are positioned in slot # 3.

Ensure the rectangular guide tab, on the bottom of the inking system, is seated in the guide slot on

the coder baseplate.

3-Replace the two mounting screws and delrin washers in the inking system baseplate. Tighten screws

just enough to allow the inking system to move by turning the inking system eccentric knob. If screws

are over-tightened, adjustment of the transfer roll pressure will not be possible.

4-Unscrew the print drum knob and remove the print drum. Replace with the appropriate print drum

and tighten the print drum knob.

5-Re-adjust the transfer roll pressure, tighten mounting screws and begin printing.
